the css to control this is in the webassist/themes/MamaBeehive/css/default_home.css file
#storeMessage {
background-image: url("../images/storeMessage_bg.png");
background-repeat: no-repeat;
height: 220px;
margin: 0;
overflow: hidden;
padding: 0;
text-align: center;
}
#storeMessage h1 {
margin-top: 80px;
}
you can change the margin-top property of the #storeMessage h1 selector and the text-align property of the #storeMessage selector.
